XPath Searching and Unions

Hi guys,

I've got another XPath question for you.  I have the following 2 XPaths both
which return results, but I wanted to union them together with a pipe( | )
but when I do that, they return 0 results.

//webfmis:content[jcr:contains(@webfmis:body,'Application')]   -- 1 result
//webfmis:file[jcr:contains(.,'Application')]  -- 1 result
//webfmis:content[jcr:contains(@webfmis:body,'Application')] |
//webfmis:file[jcr:contains(.,'Application')]  -- 0 results

I'm not sure if I'm missing something or if maybe this functionality isn't
implemented in JackRabbit yet?

Thanks,
Sean

Hi Sean,

the union operator is not supported and jackrabbit should actually throw an 
exception. see: https://issues.apache.org/jira/browse/JCR-522
